JOHN M. FALLIS, OF INDIANOLA, IOWA, ASSIGNOR OF ONE-HALF TO JOEL T.HUFFMAN, OF SAME PLACE.

S H OVEL- PLO'W.

SPECIFICATION forming part of Letters Patent No. 243,231, dated June 21,1881.

i Application led April 27,1881. (No model.)

To all whom it may concern;

Be it known that I, JOHN M. FALLIS, of Indianola, in the countyof'Varren and State of Iowa, have invented an ImprovedCultivator-Shovel, of which the following is a speciication.

My invention relates to the manner of reenforcing a shovel-plow orcultivator-shovel so as to prevent it from breaking, to protect 1o itspoint from wear, and also to facilitate the repointing and temperingthereof.

Heretofore blanks for cultivator shovels have usually been cut from asteel bar having a longitudinal swell in its center, that formed I5 anintegral rib along the entire longitudinal center of each shovel-blankcut therefrom, to strengthen it and to aid in protecting and retting itspoint; but such a surplusage of metal along the entire length of theshovel is 2o a needless expense, and produces a heavy,

clumsy shovel.

I do not claim, broadly, the welding of a reenforcing piece of metal tothe back ot' a shovel-blade or cultivator-tooth, for I am aware that itis not new to weld steel or other metal for such uses as to providemetal for renewing the point or edge of tools, for strengthening partsexposed to greatest strain, and for many kindred objects.

My invention is intended to apply wellknown methods to the specificproduction, in a rapid and cheap manner, ot' a shovel-blade of improvedand superior quality; and my object is to provide an improved, light,strong, and durable wrought-metal shovel-plow, by

re-enforcing blanks of common form cut from flat plate metal of uniformthickness, iu such a manner that the cutting-edges, point, and entirefront face can be more readily tempered 4o and made hard enough to scourwell, while the part of the complete shovel-plow that is subjected tothe greatest strain remains comparatively soft and retains its tenacity.

Figure l of my accompanying drawings is a back view of one of myimproved shovels. a is the upper and dat portion, and b the lowertapering and pointed portion, of a shovelblank of common form. crepresents a lozenge-shaped re-enforcing piece, welded upon 5o the backof the blank a b in such a position that its upper point extends upwardover the lower portion of the part a., downward toward the point of theshovel, and laterally toward its parallel edges.

Fig. 2 is a longitudinal sectional view, taken through the line d d, andFig. 3 is a transverse view, taken through the linex of Fig.

Fig. 4 is a transverse view, showing the reenforcing piece composed oftwo leaves or layers, c and c.

Figs. 5, (5, and 7 are detail views, showing modied forms of there-enforcing piece e.

While the lozenge shape is preferred, that particular shape is notessential in accomplishing the results contemplated, and the enforcingpiece to the shovel-blank to produce my im proved cultivator-shovel.

To apply the re-enforcin g piece c to the back of the shovel-blank a b,1 simply place it in proper position, as shown in Fig. 1, and weld fastin a common way by means of heat and beatino` u on an anvil in such amanner as to b I s produce a smooth Joint and even surface along theentire edge of the re-enforcing piece.

And

when the re-enforcing piece is thus solidly united with the blank thecomplete shovel can be shaped and tempered in a common way, so as toproduce a hard and polished front face that will readily scour in thesoil, while the heavy and re-enforced portion that is subject to strainwill remain soft and tenacious and free from brittleness, andconsequently strong and durable. And when the pointbecomes blunt, metalcan be readily drawn from the swell formed by means of the re-enforcingpiece to renew and sharpen the point without welding a point on, as isnow commonly practiced in relitting cultivator-shovels. I claim as myinvention- As an improved article of manufacture, a

wrought metal shovel -plow or cultivatorshovel having a re-'ent'orcingpiece, c, permanently fixed on or united with its back and lowerportion, substantially as shown and described,

for the purposes specified.
